normal symptoms?

Hi ladies! So, Im in the middle of my 9th week of pregnancy and I am feeling a bit odd. I had really sore breasts, until about a week ago, it went away. I have had no morning sickness at all, but am on an every 2-3 hour eating schedule or else Im absolutely starving! My concern though is how my breasts arent bothering me anymore and they seem back to normal all of the sudden. Also, I was constipated for a few weeks, and now, the exact opposite. going maybe 3 times a day and not so solid anymore. Is all of this normal? I have my next OBGYN apppointment next week and I just found out yesterday that we cant get an ultrasound so see if everything is ok. I would love some feed back from anyone or even just positive thpughts :) thanks ladies!!
